- I think the take home message is that you don't need the equipment to build a choke, if it's from a design that someone else HAS measured. If you want to try something new, and it works, great. Howev

- Hi Arnie, I guess there has been a discussion on baluns going on. Let me add a few comments on the subject. First off, there are alternatives or choices on transmission line types used in coax baluns

- A good choice for toroidal baluns as well as VHF/UHF 1/2 wave baluns is expanded PTFE (ePTFE) since it is very flexible and does not exhibit the center conductor flow of solid dielectric. It also exh
